Hello, I would like a website where customers can pay to download rental property documents, such as leases, applications, late notices, etc. There are a few things that are very important to me:

1) customers be able to pay with credit cards
2) the site show up as high as possible on google search results
3) a google adsense banner be added
4) emails to the site be forwarded to my personal email address
5) I be able to make updates to the site on my own once it is up and running

Do you have a general idea of what this project would cost and whether or not you would be able to help me with it?
